Description

The invention relates to a device for connecting accessories Hearing parts with formwork panels, compensating elements and the like Formwork elements facing away from the formwork skin Side stiffening webs or profiles, the front direction has a substantially U-shaped cross section and the U-leg attachment points for accessories such as Gur or the like. have and the U-crossbar in the use position a stiffening profile of the formwork.

From DE-PS 33 33 619 formwork for rotunda be knows which of the supports supporting the formlining a bar chain with bars adjustable in length is seen, these bars of the bar chain each over Grasp the connectors on the beams of the formwork panels and have an approximately U-shaped cross section. These connectors have the Be in their U-legs facing away from the formwork fixing points for the individual bars.

For the attack on the stiffening girders or profiles however, these connectors require additional couplings parts, which in turn are approximately U-shaped and the Aussti  embrace the management board. Above all, there is an attachment biger accessories such as support directed against the floor tongues, consoles or the like. not with these connectors possible because they are firmly connected to the individual bars stay.

The invention has for its object a device of the type mentioned at the beginning, with what problem any accessories such as tapes, consoles, Ab supports and the like can be quickly and easily attached to formwork panels can be consolidated, with the orientation of the exit junction bars or profiles either vertical or hori should be zontal.

The solution to this seemingly contradictory task in a device of the type mentioned at the beginning, that at least one of the U-legs on the in use position of the formwork facing side over at least egg NEN part of its length a continuation on the U-cross bar also has which continuation as anti-rotation is provided and on the longitudinal side surface of the Aussti tion profile or the edge or bend at the transition from a rear web to the long side surface of this off Stiffing profile can be applied, and that the U-crossbar Device at least one perforation for the passage of a Has shaft of a fastener, which Be Fixing element radially at least on one side head or the like protruding over this shaft. has and of the side facing away from the formwork skin by a through break of the stiffening profile insertable in this and with his head is anchored to it and to his head opposite end a counter stop for anchoring to the Has U-shaped device.  

So, in an apparently contradictory way, at least protrudes one of the U-legs of the Vorrich with a U-shaped cross section tion beyond the U crossbar, but thereby allows twist-proof coupling with the help of the fastening element on the stiffening profile, so that easily and without too additional measures for such an anti-rotation device bige parts in turn attached to this device that can.

Using only part of the length of the U- The leg-running continuation has the very high Lichen advantage that the device is also rotated by 90 °, i.e. with approximately at right angles to the longitudinal extent of the exit U-legs running on the stiffening profiles can be fixed, so that this stiffening pro file can run both vertically and horizontally, the device according to the invention in such Schalta can be used as desired, even in a 90 ° rotated position Position should be usable or intersecting exit have profiles.

The fastening element for anchoring the device to ei nem stiffening may have a hammer head ges in an orientation position through a long hole of the Querste of the stiffening profile is insertable and - for example 90 ° - twisted engages behind the edges of the elongated hole. This results in a particularly fast and effective coupling between the device and a stiffening profile provided with corresponding elongated perforations.

A particularly effective anti-rotation device with the Mög ability, correspondingly high forces and moments in the off initiate stiffening beam and thereby the device in two positions each rotated by 90 ° To be able to use the same advantage, it is advisable  if both U-legs of the device have continuations, that extend beyond the U-cross bar and if this against are shortened over the entire length of the U-legs and with the U-crossbar a - preferably approximately step-shaped - Form paragraph and outside of the neighboring area of the There are holes for the fastener. In one Assembly position these two continuations of the U- Legs over the long sides of the stiffening profile and so a very safe and good anti-twist device in create two conceivable directions of rotation, creating high force te and moments can be transferred. In contrast, the heels of the ver shortened U-legs both to a common long side Nes stiffening profile are created, which in turn an anti-rotation device and the possibility of transmission created by moments, the distance between the two Continuations of each other and of the fastener an effective and anti-twist anchorage of the front direction on the stiffening profile, which thereby at least three points opposite the stiffening profile is set. This arrangement and design of the front direction is therefore of particular importance tion to.

The distance between the U-crosspiece and the continuation of the U-legs kel can be used to prevent rotation against the long side of the off stiffening profile can be applied and in the distance from the holes for the fastener that the Slotted hole or the like Breakthrough in the stiffening profile of that Has the beginning of the longitudinal web of this profile. This results in automatically that twist 90 ° against each other in both the fastening positions of the front direction come into effect, since they are attached with the fastener on the long side of the off stiffness profile.  

The better the anti-rotation lock, the more effective it is Device is pressed on a stiffening profile. It can be useful if the on the U-crossbar Device attacking counter stop for fastening element can be clamped with this. This counter can stop releasably on the shaft of the fastener to grab. In this way, he can also subsequently, if that Fastener and his head through the breakthrough Stiffening profile is inserted and twisted, attached will.

As a counterstop at the end of the befe facing away from the head Stigungselementes a transverse slot through its shaft and a wedge that can be inserted therein, the Cross slot in the use position preferably up to the Lo Chung the crossbar of the device is sufficient. This is easily created a concrete solution for that the counterstop against this U-crossbar the front direction is braced. The wedge only needs to be deep enough to be hammered in to a corresponding pulling force the shaft and thus also on the head of the fastening element exercise mentes and against the U-crossbar of the device to press that of the stiffening profile.

By the length of the fastener and thus the total to be able to keep the dimensions of the device as small as possible, it is advantageous if in the use position of the cross slot in the shaft of the fastener between the U-legs of the device on the formwork facing away th side of the U-crosspiece is arranged and the U-legs breakthroughs of the device at the height of the transverse slot for the anchoring wedge. This can be done through the breakthroughs to be inserted into its ge use position in the transverse slot of the shaft of the fastening supply element to arrive.  

A further expedient embodiment of the device can consist in that the cross section of the transverse slot for the wedge on the shaft of the fastening element is arranged rotated relative to its hammer head - or by 45 ° - and the openings on the U-legs of the device are such staggered arrangement and / or lateral expansion that the wedge runs obliquely from one leg through the anchoring slot of the fastener to the other opening. Thus, the wedge can be driven in with an oblique seat in such a way that it is held in its position of use by gravity. This not only makes assembly easier, but also counteracts accidental loosening.

A further advantageous embodiment can be therein stand that the breakthroughs for the wedge on the U-legs the device have such a lateral expansion or that there were so many breakthroughs next to each other hen are that the wedge obliquely from both sides to the upper area of the U-leg and at least in two preferred positions that can be used offset by 90 ° is. This can take into account the possibility the device in two 90 ° different positions Stiffening profiles can be applied depending on whether these stiffening profiles are approximately vertical or approximately hori run zontally. In each of these cases it can be achieved be that the wedge slants from top to bottom and not runs approximately horizontally or even from bottom to top.

The attachment points for the detachable connection of accessories can share as recesses, preferably holes forms and on the U-legs of the device at a distance the openings for the anchoring wedge. However, it should be noted at this point that, if applicable a nut as a counter on the shaft also via a thread  stop could be provided if the U-leg not enough space on the one hand for the breakthroughs for the Offer wedge and on the other hand for the attachment points should.

There can be one attachment point on each U-leg be seen and both attachment points can be preferred wise have the same shape and position, esp Special or the like as holes for a push-through bolt. be trained. This can then be part of an accessory part that reaches between the two U-legs, enforce and on both sides of this captured part of the accessory hearing part to be anchored to the U-legs.

A particularly simple and good securing of the attachment element of the device arises when the inside side of the U-crossbar facing the stiffening profile Surfaces of the head of the connecting bolt according to a sik conical or trough-shaped indentation of the U-crosspiece of the Bracing profile obliquely from the shaft to the outside fen. At the same time, this increases the rigidity of the ejector tion profile, so that it is all the better to add allow about the device according to the invention.

It is useful if the continuations of the U-legs consist of one piece with these. Then the U-crossbar of the device between the U-legs and de Ren continuations inserted, especially welded his and his in use position on the outer web of the Stiffening profile adjacent surface can with the discontinued area of the U-legs more appropriate wise to be flush. This results in a rigid construction tion in particular of the U-shaped part of the fiction moderate device.  

It should also be mentioned that the perforation for the attachment element is expediently a hole because this be is particularly easy to manufacture and also one accordingly simple round shaft of the fastener allowed. However, this bolt-shaped fastener can between its shaft, which is preferably round in cross section and the roof-shaped inclined surfaces on the lower side of his head a square area as a twist securing for engaging in the recess of the crossbar of the Have stiffening profile. This will facilitate that the cross slot for the anchoring wedge after insertion and setting the head of the fastener its Retains the position and thus the oblique insertion of the wedge from the Side is relieved.

To save weight, the U-legs of the device between their end faces and their facing away from the crossbar th edges outside the openings for the anchoring wedge and the mounting holes for the accessories be chamfered.

Especially when combining one or more of the above written characteristics and measures results in a Vorrich device with which any accessories on formwork elements elements can be attached, the corresponding exit have bars and profiles, these accessories Straightening struts, running consoles, climbing consoles, trestles, Floor supports or straps can be. The Device their attachment in two ge preferably by 90 ° mutually twisted positions so that they with their U-legs and the attachment points in each case Can be tiert, as is the attachment of the accessories makes necessary, regardless of whether the off stiffening profiles of the formwork panels in turn vertical or are oriented horizontally. Also on slab formwork  corresponding stiffening profiles can this device to be ordered. This results in every attachment position a functional and firm connection between the accessories and the formwork element, but not only Forces, but due to the good anti-twist protection also Mon elements can be transferred.

Below is the invention with its as essential associated details based on the drawing in an Aus example described in more detail. It shows in to Part of schematic representation:

Fig. 1 is an exploded view of the erfindungsge MAESSEN device prior to its mounting on a hori zontal oriented stiffening verti cal a standing formwork panel and prior to attachment ei nes accessory part, in this case a brace thereto,

Fig. 2 is a rear view of the device was assembled in to, said horizontally extending Ausstei are omitted Fung profile and the accessory of the better Deut friendliness due, but a slot is indicated in the reinforcing profile,

Fig. 3 a section through the U-crosspiece of the device and the vicinity of a stiffening profile of this device as well as a view of a U-limb and its rotation as extending only over part of the length of continuation,

Fig. 4 is a view of the entire device in an orientation for the attack on a vertically running stiffening beam or profile and

Fig. 5 is a plan view of the device in an assembly position on a vertically extending stiffening profile or in a position in which the two over a part of the length of the U-leg of the Vorrich device continuations the longitudinal Seitenflä surfaces of the stiffening profile as an anti-rotation spread.

A device designated as a whole with 1 is used to bind accessories, for example a strut 2 with formwork panels, compensating elements or the like. Schalungsele elements that are not shown in the drawings and have stiffening webs or stiffening profiles 3 on their side facing away from the formlining. These Ausstei tion profiles 3 are. With respect to the entire cross-section at playful in Fig. 1 and. With respect to their cooperating with the device area in FIGS . 3 u. 5 recognizable.

Referring to Figs. 1 and particularly Fig. 5 it is clear that the device 1 has a U-shaped cross-section and substantially their U-legs 4 mounting points 5 or the like for the accessory parts such as booms, directional struts 2. to have. The U-cross bar 6 is shown in FIG. 3 u. 5 in the use position on the stiffening profile 3 of the formwork.

When comparing Fig. 2 u. 3 on the one hand with FIGS. 4 u. 5 on the other hand, it can be seen that provision has been made for the device 1 to engage in two different positions rotated against one another by 90 ° on a profile 3 or the attachment to profiles 3 differently oriented by 90 ° in a corresponding position is possible. At the same time, a good anti-rotation device 1 is given relative to the profile 3 , so that the forces and moments to be transmitted can be initiated well.

This is achieved in that the U-legs 4 on their side facing the formwork facing each have a continuation 7 over the U-transverse web 6 over part of their length, which continuations 7 are provided in both mounting positions as anti-rotation devices. These continuations 7 are shown in FIGS. 3 u. 5 in two different ways on the long side surface 3 a of the stiffening profile 3 or the edge or bend at the transition from a rear web 3 b to the long side surface 3 a of the stiffening profile 3 can be applied.

Furthermore, the U-cross bar 6 of the device 1 has a perforation 8 for the passage of a shaft 9 a of a Befestigungsele element 9 , which also has a head 9 b projecting at least on one side, in the exemplary embodiment on two sides radially beyond this shaft 9 a . With this head 9 b ahead, this fastener 9 can be inserted from the side facing away from the formlining through an opening 10 in the form of an elongated hole in the stiffening profile 3 and with its head 9 b in FIG . Anchor it in a recognizable way. At the head 9 b abge facing end of the fastener 9 , a counter-stop to be described for anchoring to the U-shaped device 1 is arranged.

The fastener 9 thus has for anchoring the device 1 on a stiffening profile 3 a hammer head 9 b , which can be inserted in the one orientation position through the elongated hole 10 of the crossbar 3 b of the stiffening profile 3 and in the exemplary embodiment rotated by 90 °, the edges of this elongated hole 10 engages behind, as indicated by dashed lines in Fig. 2.

When comparing FIGS. 3 to 5, it can be seen that both U-legs 4 of the device 1 have extensions 7 which extend beyond the U-crosspiece 6 and that these correspond to the total length of the U-legs 4 in a matching manner and with a matching dimension are shortened and with the U-cross bar 6 form an approximately step-shaped shoulder 11 (see. In particular. Fig. 3 and 4) and are located outside the neighboring area of the perforations 8 for the fastener 9 be.

As shown in FIG. 5 with their own longitudinal extension 3 may act as anti-rotation sequels 7 directly to the longitudinal sides 3a of the off steifungsprofiles when the U-arms 4 and the reinforcement profiles 3 have a matching direction of orientation can be in a twisted by 90 ° assembly position the U-limbs serve as shown in FIGS. 1 to 3 of paragraph 11 between U-crosspiece 6 and continued 7 or between non-continuing region of the U-legs 6 and continued 7 to prevent rotation relative to the longitudinal side 3a of the stiffening profile 3, as be particularly clearly in Fig. 3 can be seen. These paragraphs 11 are located at a distance from the perforation 8 for the fastening element 9 , which the elongated hole 10 in the stiffening profile 3 each have its longitudinal webs 3 a or the beginning of the cross bar 3 b . It is thereby achieved that in the position in which the U-legs 4 of the device 1 are rotated by 90 ° with respect to the longitudinal extent of the profile 3 , the shoulders 11 bring about the desired anti-rotation and come into contact with the profile 3 .

The already mentioned counter-stop for the Befestigungsele element 9 should be clamped to the U-crosspiece 6 of the device 1 with the sem or the fastening element in order to be able to press the device 1 firmly against the profile 3 and to make the anti-rotation devices effective. It is advantageous if this counter stop detachably engages the shaft 9 a of the fastening element. In the game Ausführungsbei it is provided that a cross slot 9 c through its shaft 9 a and as wirkli cher counter stop a in this cross slot 9 c suitable and insertable wedge 12 are provided as a counter-stop on the head 9 b facing away from the fastener 9 , wherein the cross slot 9 c in the use position extends approximately into the perforation 8 of the crossbar 6 of the device 1 . When Einschla gene of the wedge 12 is ensured by the fact that the U-crosspiece 6 is 6-facing narrow side of the U-crosspiece to the system and can exert with the opposite narrow side of the desired tractive force on the shaft 9 a.

So that the entire device 1 does not get too large dimensions and does not attack with too large lever arms on the profiles 3 , in the exemplary embodiment, the transverse slot 9 c is arranged between the U-legs 4 and the U-legs 4 of the device 1 have at the level of Cross slot 9 c openings 13 for the anchoring wedge 12 . These also extend so far against the formwork that the facing away from the surface of the U-crosspiece 6 lies in the Lich th inner contour area of these openings 13 so that the wedge 12 comes to this surface of the U-crosspiece 6 .

However, it would also be conceivable that the wedge comes to bear on the corresponding limits of these openings 13 , in particular if the slot 9 c would not extend into the perforation 8 or even beyond.

Especially FIG. 2 on the basis it can be seen that the cross section of the transverse slit 9c for the wedge 12 on the shank 9a of the fastening element 9 b against the hammer head 9 is disposed at about 45 ° twisted and the openings 13 to the U limbs 4 have such a lateral extent that the wedge 12 runs obliquely from one leg 4 through the anchoring slot 9 c to the other leg 4 and its opening 13 . In both possible orientations of the device 1 , it can thus be arranged obliquely from top to bottom, which above all facilitates assembly because a first insertion of the wedge is supported by gravity. Furthermore, the position of use is supported by gravity and better secured and an unwanted falling out of a Kei les 12 avoided. In addition, a locking pin 14 can be provided at the narrow end of Kei les 12 .

The oriented in the longitudinal orientation of the U-legs 4 since Liche expansion of the openings 13 is so large that the wedge 12 from both sides obliquely to the surface of the U-legs 4 and can be used in two positions offset by 90 °, in order not to have to pay attention to the position of the transverse slit 9c at the previous insertion of the fastener. 9 Instead of the accordingly extended recesses or apertures 13 and a plurality of apertures 13 adjacent to each other may be provided to these two angular positions of the wedge 12 to ermögli chen.

In the exemplary embodiment, the fastening points 5 are designed as recesses or holes and are arranged on the U-legs 4 of the device 1 at a distance from the openings 13 for the anchoring wedge 12 . In this makes particularly Fig. 1 shows that at each U-leg 4 a fastening point 5 is provided, and both fastening locations have 5 same shape and matching able beispielswei se are formed as holes for through bolts, which also through corresponding holes 15 the directional strut 2 fits, which in turn can be inserted between the two U-legs 4 . Thus, this strut 2 or another accessory with its coupling area and its corresponding attachment point 15 inserted between the U-legs 4 and there with a push-through bolt zen through all attachment points 5 u. 15 are anchored through. You can then absorb or transmit forces and moments that are introduced by the device 1 in an advantageous manner without the risk of twisting or evasion into the profiles 3 , or conversely, the outgoing forces from the profiles 3 and the formwork panels in this way via the Device 1 or the like on such a strut 2 . be transmitted.

Although other solutions are possible, it is provided in a practical manner in the exemplary embodiment that the continuations 7 of the U-legs 4 be with these in one piece. The U-transverse web 6 of the device 1 is inserted between the U-legs 4 and their continuations 7 and welded and its surface in the use position on the outer web 3 b of the stiffening profile 3 is surface with the discontinued area of the U-legs 4 is preferably approximately flush or, according to FIG. 4, even protrudes somewhat.

The perforation 8 for the fastener 9 is in the example Ausfüh approximately a hole that is particularly easy to attach bar.

Fig. 1 shows that the bolt-shaped Befestigungsele element 9 between its cross-sectionally round shaft 9 a and the roof-shaped inclined surfaces on the underside of its head 9 b a square area 9 d as a twist protection for engagement in the recess 10 of the crosspiece 3 b of the Stiffening profile 3 has. Both the inclined surfaces on the head 9 b and this angular area 9 d stabilize the position of the fastening element 9 , thus the wedge 12 and also the entire device 1 and thus improve the transmission of forces and moments.

In Fig. 1 it can also be seen that the U-legs 4 of the device 1 between their end faces 4 a and their edges facing away from the crossbar 6 4 b outside the openings 13 for the anchoring wedge 12 and the fastening holes 5 for the accessories 2 beveled can. This saves weight and an unfavorable protrusion of the device 1 compared to the profiles 3 and the accessory parts len 2 limited as much as possible.

A device 1 is used to connect accessories 2 with formwork panels, compensating elements or the like. Schalungsele elements that have on their side facing away from the formlining from stiffening webs or stiffening profiles 3 . The device 1 has an essentially U-shaped cross section, its U-legs 4 attachment points 5 , preferably holes, for the accessories 2 such as harnesses, struts, running consoles or the like. and have the U-transverse web is tightened and in use position to a stiffening profile 3 and primarily a provided on this profile 3 transverse web 3 is applied b. 6 At least one of the U-legs 4 , preferably both U-legs 4 , has on the side facing the formwork skin over a part of its length a continuation 7 beyond the U-crosspiece 6 , which is provided as an anti-rotation device and on the Longitudinal side surface 3 a of the stiffening profile 3 or the transition from the rear web 3 b to the long side surface 3 a can be applied. The U-crosspiece 6 of the device 1 has at least one - possibly even open edge ne - recess or perforation 8 for the attack of a fastening supply element preferably for the passage of the shaft 9 a of a fastening element 9 . This makes it possible to anchor the device 1 in a position secured against rotation in two positions rotated by 90 ° on a stiffening profile 3 , so that the forces and moments that occur can be transmitted well.

An embodiment essential to the invention can still be seen particularly in FIG. 5 and also in FIG. 2. Thereafter, the continuations 7 relative to the parallel U-webs 4 are issued somewhat obliquely to one another in order to adapt well to the trapezoidal shape of the stiffening profile 3 and the corresponding to obtain oblique orientation of the cross section of the side webs 3a of the stiffening profile. 3 The Innenabmessun gen this slight angle to each other sequels 7 correspond to the external dimensions of the two longitudinal webs 3a of the stiffening third

In the figures you can still see that the wedge 12 in Ge use position with its narrower area penetrates a U-leg and its recess 13 , with its wider area but passes by the opposite U-leg and its end face on the outside or even supports. It is therefore not necessary for the wedge to pass through one of the recesses 13 at the same time, but only selectively.
